Description

Steering device for caterpillar vehicles, addendum to the patent «....... ♦. · (Application ρ 13 S9o dated l» lo.48).

The invention relates to a further embodiment of the steering device

for caterpillar vehicles with patent ....... ♦ (registration ρ 138 * 3α

from 1 · 1ο.48.)

The main patent provides for excavators and other heavy vehicles a caterpillar undercarriage, which is designed for negotiating curves, i lid em the stretches of the loupe belts that protrude over the two sides of the chassis in the longitudinal direction are laterally adjustable so that they can be moved around curves arranged chassis running on the lower TUupenbahn can be presented not only straight, but also curved track-like »

With such crawler tracks, the load of the superstructure is BEZW with the interposition of all sides. Connecting parts that are movable on both sides are transferred to the individual pressure rollers by means of compensating levers and from these to the crawler tracks. Here are

direction

summarized in general in two FahrtIhintereinanderliegende pressure rollers by means of a ..usgleichhebele pairs, when driving on curves, the track is curved corresponding to the curve to befahrenflen Iooe but laid on the ground in accordance with the Iiauptpatent. It is necessary to provide the pressure wheels with a bearing that guarantees that the pressure wheels, which are guided by the crawler belt, do not act on the loosely laid crawler belt in the manner of a track-moving machine. The play between the crawler belt and the pressure wheel must not be too great, as otherwise the pressure rider misjudges the intended direction of travel.

After Srfiradteag TOrgeschlagea _i hei Gleieketttafahrseug '' ait at least ei "juxtaposed Sleietetten and ait pairs summarize the hintereinanderliegenäen Bruofcrider! ea AusgleielihelielB _t to the constricting by further about lie balance lever, the load of the superstructure is distributed form "the steering device so that the swingable in the vertical Kbene, two successive running Bruölcräd ^ r sueafflnenf & esenden balance lever with respect to the bogie" BEZW * Fahrgeetellrahmen about a vertical axis Brehbar are. With such crawler vehicles, in cleneu 3 one after the other running Bruckrääer to a bogie JOINT as are st, is vegetable to a further embodiment proposed by the invention is that Ewei juxtaposed print wheels are adjustably mounted on the ends of a transversely arranged to the direction AusgleiehhebeIs, the em on a! - -. In the direction of travel journal of a compensating lever Is is pivotably mounted, which at its other end the compensating levers of two arranged next to each other «!! pairs of gusam «ng © faseten pressure wheels are supported by us & in which the equalizing lever above is held in a vertical guide.

What is achieved with the invention is that the individual pairs of pressure wheels can adapt to the caterpillar track laid in the curve without any constraints. They are thus tangential or approximately tangential to the curve. As a result, a lei elite, wear-saving driving is achieved even in curves. The invention enables these advantages without the use of expensive Components.
